将 Terraform Cloud Build 触发器构建步骤配置到 GCP 项目

Question

在我的开发中，我正在测试是否有办法将 cloudbuild.yaml 构建步骤 (Terraform) 复制到 TerraForm Cloud Build Trigger Build>Step 资源。我已经关注了

resource "google_cloudbuild_trigger" "build-trigger" {
provider = google-beta 
project = var.project
 github { 
      owner = "github repo"
      name = var.name
    push {
        branch = var.branch
    }
}

build {
    step {

      id = "branch name"
      name = "alpine"
      entrypoint = "sh"
      env = [
      {
          BRANCH_NAME = var.branch
    }
      args = [ "-c" ,  "echo ${BRANCH_NAME}" ]
         }
  




 } 
    
   description = "Push to any branch"
   filename = "cloudbuild.yaml"
}

steps:
- id: 'branch name'
  name: 'alpine'
  entrypoint: 'sh'  
  args: 
  - '-c'
  - | 
      echo "***********************"
      echo "$BRANCH_NAME"
      echo "***********************"

# #   #[start tf-init]
- id: 'tf init'
  name: 'hashicorp/terraform:0.13.0'
  entrypoint: 'sh'
  args: 
  - '-c'
  - |
      if [ -d "environments/$BRANCH_NAME/" ]; then
        cd environments/$BRANCH_NAME
        terraform init
      else
        for dir in environments/*/
        do 
          cd ${dir}   
          env=${dir%*/}
          env=${env*/}
          echo ""
          echo "*************** TERRAFORM INIT ******************"
          echo "******* At environment: ${env} ********"
          echo "*************************************************"
          terraform init || exit 1
          cd ../../
        done
      fi 
  
# # [START tf-plan]
- id: 'tf plan'
  name: 'hashicorp/terraform:0.13.0'
  entrypoint: 'sh'
  args: 
  - '-c'
  - | 
      if [ -d "environments/$BRANCH_NAME/" ]; then
        cd environments/$BRANCH_NAME
        terraform plan
        
      else
        for dir in environments/*/
        do 
          cd ${dir}   
          env=${dir%*/}
          env=${env*/}  
          echo ""
          echo "*************** TERRAFOM PLAN ******************"
          echo "******* At environment: ${env} ********"
          echo "*************************************************"
          terraform plan  || exit 1
          cd ../../
        done
      fi 
  
 #  # [END tf-plan]

# #[START tf-apply]
- id: 'tf apply'
  name: 'hashicorp/terraform:0.13.0'
  entrypoint: 'sh'
  args: 
  - '-c'
  - | 
      if [ -d "environments/$BRANCH_NAME/" ]; then
        cd environments/$BRANCH_NAME      
        export TF_LOG=TRACE
        terraform apply -auto-approve 
      else
        echo "***************************** SKIPPING APPLYING *******************************"
        echo "Branch '$BRANCH_NAME' does not represent an oficial environment."
        echo "*******************************************************************************"
      fi

# [END tf-apply]  

我得到的错误是

On ../../modules/services/CloudBuildTriggers/cloudbuildtrig.tf line 22:
Expected a comma to mark the beginning of the next item.

如何在云构建触发器的构建步骤中简单地放置 bash 命令？ 还是只引用了 GCLOUD SDK 命令？

Answer 1

正确的解决方案是不使用 {}，然后在 bash 脚本的开头和结尾使用 EOF 或 EOT。

 build {
    step {
      id          = "branch name"
      name        = "alpine"
      entrypoint  = "sh"
      args        = [
        "-c",  
<<-EOF
  echo "***********************"
  echo "$BRANCH_NAME"
  echo "***********************"
EOF
      ]
    }
    step {
      id          = "tf init"
      name        = "hashicorp/terraform:0.13.0"
      entrypoint  = "sh"
      args        = [
        "-c",
<<-EOF
if [ -d "environments/$BRANCH_NAME/" ]; then
  cd environments/$BRANCH_NAME
  terraform init
else
  for dir in environments/*/
  do
      cd $dir  
      env=$dir%*/
      env=$env#*/
      echo ""
      echo "*************** TERRAFORM INIT ******************"
      echo "******* At environment: $env ********"
      echo "*************************************************"
      terraform init || exit 1
      cd ../../
  done
fi
EOF
      ]
    }

这里 [1] 有一些关于运行 bash 命令的信息，这里 [2] 有一些关于创建和管理触发器的信息。 另一方面，您可能会在 terraform 社区 [3] 上询问，因为它可以帮助解决错误消息。
